Ultra compact passive sub bass for mobile audio or permanent installation, the HPI-12S is hard to beat. Light in weight and high in LF output, the HPI-12S is ideally suited to small medium sized venues that require authentic sub bass with a very low visual profile. Internal rigging points allow the sub bass to be flown for permanent ceiling installation and the 35mm top hat can accommodate a standard speaker pole for mounting a satellite mid-high box. Power handling is high for such a small system with a power amplifier recommendation of 600W nominal. The HPI-12S passive sub bass is the ideal partner to any of the HPI's small format satellite systems. It can also be powered with any of Quest Engineering's excellent range of power amplifiers which encompass internal cross-over features.
